Instead of substring() function what can I use in matlab R2016b












1















I want to implement the following statement in Matlab R2016b 



file_a = substring(char(file_a), 0, findstr(char(file_a), '_')-2);


Here, file_a having 101_1 to 101_8, 102_1 to 102_8 and so on.



substring() is not evaluated in the R2016b release.

          What exactly is your expected result?



          file_a = '101_1'
          
file_a = extractAfter(file_a,strfind(file_a,'_')-2)


          this code produces a file_a of '1_1'.



          file_a = '101_1'
          
file_a = extractBefore(file_a,strfind(file_a,'_')-1)


          this code produces a file_a of '10'



          file_a = '101_1'
          
file_a = extractBetween(file_a,strfind(file_a,'_')-1,strfind(file_a,'_'))


          this code produces a file_a of '1_'
